You can order the PCBs with such coating

We use something we name 'elephant snot'. Easily removed after soldering. I will try to find what's the products real name.

Henry,
What about a temporary solder mask?

Subject: [TN] Pad that does not solder.
Hi,
I have an application where I need to force a pad to not solder (or at least solder to a consistent thickness) in wave solder. The pad will eventually recieve a mechanical connection. I'm trying to design a land that will either skip, or solder to a consistent minimum thickness. The pad is large about 0.500 by 0.500. Maybe some sort of a checkerboard, or grid of vias, etc? The wave is leadfree with sac solder.
Selective soldering has already been ruled out due to other design constraints, and I'm also pursuing the idea of peelable mask.
Any ideas?
Thanks.
Henry.
